如何从Laravel 5.5中的3个表中获取所需的行

I have 3 tables, Order, Products, Order_Products. I need get all field from order and products, thats ok using hasManyThrough(). But i need 1 more field from Order_products. How can i get this field ?

public function products()
{
   //in order model
 return $this->hasManyThrough('App\Models\Product','App\Models\OrderProduct','order_id','id','id','product_id');
}

using sql i need query like

SELECT products.*, order_products.order_id, order_products.count as order_count FROM products INNER JOIN order_products ON order_products.product_id = products.id WHERE order_products.order_id = 2

You can access intermediate table fields by using pivot attribute on model.

Lets say you have product, Then you can access count field of orders_products

$product->pivot->count;
